The inferior colliculus is a small, paired structure located in the midbrain, part of the auditory pathway. It plays a crucial role in processing auditory information, particularly in integrating sound from both ears to help locate the source of sounds in the environment. In addition to its role in hearing, the inferior colliculus is involved in reflexive responses to sound, such as turning the head towards a noise. It acts as a relay station, sending auditory signals to other areas of the brain, including the thalamus and cerebral cortex, for further processing and interpretation.
